چکیده
The title compound, C(12)H(9)FN(2)O(2), was prepared by the reaction of 2-fluoro-benzaldehyde and furan-2-carbohydrazide. The furan ring is disordered over two sets of sites with refined occupancies of 0.60 (3):0.40 (3). The major and minor components of the furan ring make dihedral angles of 51.9 (6) and 38.0 (10)°, respectively, with the benzene ring. In the crystal, mol-ecules are linked via bifurcated N-H⋯O(N) hydrogen bonds into chains along [001].

The title Schiff base compound, C(9)H(12)N(2)O(2), was obtained from a condensation reaction of butan-2-one and furan-2-carbohydrazide. The furan ring and the hydrazide fragment are roughly planar, the largest deviation from the mean plane being 0.069 (2)Å, but the butanyl-idene group is twisted slightly with respect to this plane by a dihedral angle of 5.2 (3)°. In the crystal, inter-molecular...
